Embodiment 1

[0033] refer to figure 1 In this embodiment, the width of the cabinet body 7 is 820mm, the height is 1850mm, and the thickness is 1150mm. By increasing the width of the cabinet body 7, the distance between phases is changed from 190mm to 210mm, so that large-capacity circuit breakers such as VTK-1250A commonly used in ground high-voltage switch cabinets The device can be installed in the cabinet body 7. All performance indicators of the switchgear can meet the relevant national standards. In this way, the growing demand for large-capacity underground high-voltage switchgear in coal mines can be met. This provides convenience for maintenance, reduces potential safety hazards, and provides greater flexibility for the design of the width of the coal mine electromechanical chamber.

[0034] The handcart room 17 is moved up about 200mm as a whole to ensure that there is no obstacle for the handcart 19 to pass in and out. Preferably, a horizontal lead screw 22 is rotated in the h...

Embodiment 2

[0046] refer to Figure 6~7 , the handcart guide rail 23 is a square frame structure connected with the cabinet body. The frame guide rail does not require any support from the ground to prevent the handcart 19 from being subjected to large vibrations during the movement. The unevenness of the ground in the electromechanical chamber has nothing to do with the push and pull of the handcart, and there is no need to adjust the level of the door body during maintenance, which reduces the workload. Preferably, a rotating track 41 is provided on the rear side of the handcart guide rail 23, and the lower end of the rotating track 41 is connected to the cabinet body 7 through a slideway 42. 90 degrees, from the vertical position to the horizontal position, so as to be in the same horizontal plane as the handcart guide rail 23, which is convenient for the handcart 19 to move in and out. The handcart 19 is also provided with a grounding socket 43 . Other structures are with embodiment...

Abstract

The invention discloses a handcart type mining flameproof high-pressure vacuum switchgear cabinet and belongs to the field of switchgear cabinet equipment. An instrument chamber door (1) and a handcart chamber door (8) are connected on the front side of a cabinet body (7) through flameproof joint surfaces, a wire-incoming flameproof shell (33) and a wire-outgoing flameproof shell (28) are connected on the rear side of the cabinet body (7) through flameproof joint surfaces, the wire-incoming flameproof shell (33) and the wire-outgoing flameproof shell (28) are arranged at an interval, outer wire-incoming binding posts (34) are arranged in the wire-incoming flameproof shell (33), and outer wire-outgoing binding posts (29) are arranged in the wire-outgoing flameproof shell (28). The instrument chamber door (1) and the handcart chamber door (8) are connected to the front side of the cabinet body (7) through the flameproof joint surfaces, the wire-incoming flameproof shell (33) and the wire-outgoing flameproof shell (28) are arranged at an interval, and an incoming wire and an outgoing wire of the switchgear cabinet are completely separated, so that flameproof performance is greatly improved, operating requirements of high-gas mine of coal mining can be met, and adaptability of contamination degree on the environment is higher.

Description

technical field [0001] The utility model relates to a mine explosion-proof high-voltage vacuum switchgear of handcart type, which belongs to the field of switchgear equipment. Background technique [0002] At present, the explosion-proof handcart type high-voltage vacuum switchgear used in underground coal mines is blank. The explosion-proof 10kV (6kV) high-voltage used in underground coal mines is powered by a high-voltage switch. With the continuous increase in the capacity of underground equipment in coal mines, high-voltage The anti-switch can no longer meet the requirements of power supply. The high anti-switch capacity is generally 630A, and the breaking current is 12.5kA. In low-gas mines, the central power distribution room generally adopts mine-used general high-voltage switchgear for power supply. In high-gas mines, according to the requirements of the "Coal Mine Safety Regulations", mine flameproof equipment must be used. The existing mine-used general high-volta...
